Conduit routing looks simple on a one-line diagram and gets complicated fast once it has to share a corridor with water, sewer, and storm lines, or thread around slab work already scheduled. GCs who confirm routing and depth early avoid the version of this problem that shows up as a field conflict instead of a plan revision.

What GCs Should Lock Down Before Conduit Goes In

Routing coordinated with water, sewer, and storm lines in the same corridor, so nothing has to be relocated after the fact.
Depth and separation requirements confirmed with the power or telecom provider, since standards vary by utility owner.
Slab and structural schedules checked against conduit stub-up locations before either one is finalized.
A clear owner for coordination between the electrical or telecom designer and the site utility contractor.

Confirming Conduit Routing Before Conflicts Appear

Overlay the conduit plan against water, sewer, and storm routing before excavation, not after a conflict is hit in the trench.
Confirm depth and separation standards with the specific power or telecom provider serving the site.
Check stub-up locations against the structural and slab schedule before either is locked in.
Sequence conduit installation relative to other underground scopes sharing the same corridor.
Assign one point of contact responsible for reconciling conduit routing with everyone else's plans.

‍

OSHA's trenching and excavation safety guidance applies to conduit trenches just as much as water and sewer lines, particularly where multiple utilities are being installed in a shared, congested corridor.

Where Conduit Scopes Commonly Go Wrong

Routing finalized without checking it against water, sewer, and storm lines sharing the corridor.
Depth or separation assumptions that don't match the actual requirements of the power or telecom provider.
Stub-up locations that don't line up with where the slab or structure ends up being poured.
No single point of coordination between the electrical designer, the GC, and the site utility contractor.

Questions GCs Ask About Commercial Conduit

How early should conduit routing be confirmed?

Before the water, sewer, and storm trenches are finalized, since conduit is often the easiest scope to reroute on paper and the hardest to fix once everything else is in the ground.

Does conduit installation need its own inspection?

Typically yes, separate from water and sewer testing, and often governed by a different agency or utility provider entirely. Confirming that requirement early avoids a scheduling surprise later.

What does RBC Utilities bring to conduit coordination?

Experience reconciling conduit routing against water, sewer, and storm work on the same site, since RBC typically installs all four scopes for a project rather than just one in isolation.

‍

The Bottom Line

Commercial conduit installation causes the most problems when it's treated as an isolated scope instead of one more system sharing a crowded corridor. Confirming routing, depth, and stub-up locations early keeps it from becoming a field conflict.
